There are a total of 20 students in the class (20 dots)

Statement 1 : Exactly 50% of the students scored 80 or higher.

If we count from 80 towards 100, we see that 14 students scored 80 or higher (not 50%) - false.

Statement 2 : More than 30% of the students failed the quiz with a score of less than 70.

There are 5 students who scored a 65 or below, which is 25% of the students (not 30%) - false

Statement 3 : Fewer than 12% of the students scored a 100.

There are 3 students who scored a 100 (15%, more than 12%) - false

Statement 4 : Exactly 75% of the class passed the quiz with a score of 70 or higher

There are 15 students who scored a 70 or more (75%) - true

So, the answer is the 4th option.

Answer:

last one

Step-by-step explanation:

20 dots in total, use as base

9 dots 80 or above, 9/20 does not equal 1/2

5 dots 65 or below, 5/20=1/4<1/3

3 dots on 100, 3/20=15/100>12/100

15 dots 70 or above, 15/20=3/4 true
